This paper presents a theoretical work, in order to apply welltested experimental correlations by Gnielinski to a lumpedparameters analysis of cross-flow heat exchanger. It producesan effective set of equations which could be useful andeffective in order to produce an accurate design of staggeredand in line heat exchangers, but also heat pipes basedexchangers. The presented method can help designer of heatexchangers to design and determinate performances of crossflow heat exchangers starting by the physical properties of apipe (or heat pipe) and using geometrical parameters of theexchanger produces an effective evaluation of performances ofthe whole exchanger.

Abstract
This paper presents a theoretical work, in order to apply welltested experimental correlations by Gnielinski to a lumpedparameters analysis of cross-flow heat exchanger. It producesan effective set of equations which could be useful andeffective in order to produce an accurate design of staggeredand in line heat exchangers, but also heat pipes basedexchangers. The presented method can help designer of heatexchangers to design and determinate performances of crossflow heat exchangers starting by the physical properties of apipe (or heat pipe) and using geometrical parameters of theexchanger produces an effective evaluation of performances ofthe whole exchanger.
